You got solid points about time and money spent, but it’s not all like that and OP has points as well.

A bidet is $20-$30. My Filipina wife asked for one, and rejected the nicer units I wanted to buy. Busted out all the tools, which some may not have, only needed simple pliers to get the old fitting loose. Rest was done by hand in 10-minutes, tested and working.

Now how much you spending on toilet paper again?

I know we can’t all grow our own food, but some things are worth looking into.

Another one; My fridge is failing. Pretty sure it’s a worn fan, but I’m clueless. As OP said, find a YouTube video.

I’ve had my AC fail a few times. It was a $20 capacitor in every case, took 45-minutes to figure out the first time. 10-minute fix now.

How much was hiring a pro to come to your house?

Hell, maybe you even got some tools you didn’t end up needing, but those are yours forever.

DIY ain’t cheap. But baby steps are a thing.

Worst case, you fail and learn.
